Can`t join any game

[Namemerken]

If i want to join a EF game it always says: "The host uses a different mod" my friend can join everyone...we got exactly the same versions ef: 1.3 and COH: 2.601.0 why i cant join EF games?

I'm not sure, but I guess there was small update after 1.3... like 1.301 or something like this.
did you or your friend modified EF files in any way? This can cause some problems...

There're a couple of updates(1.301 && 1.302) that you need to download/install after 1.30 is installed.

Also, make sure you aren't using skin mods.
